Non-global logarithms in hadron collisions at Nc = 3

Non-global logarithms in hadron collisions at Nc = 3

We calculate the rapidity gap survival probability associated with the Higgs decay and Higgs plus dijet production in proton-proton collisions by resumming the leading non-global logarithms without any approximation to the number of colors. For dijet production, depending on partonic subprocesses, t...
